To all whom it ntay concern.-

I Be it known that we, JOSEPH SNYDER, of West Pittston, and DA'rHAN MORSE, of Hugheston, Luzerne county, Pennsylvania, and citizens of the United States, have invented certainnew and useful Improvements in Coal Cleaners; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the are fixed, is of polygonal shape in section, and the eyes of the disks and flanges are of polygsame.

Our invention consists in a device for separating culm and slate from coal as it comes from the screen. The chief parts of our coalcleaner, and to which our improvements relate, are an inclined chute, acleaning-roll composed of alternate disks and flanges of peculiar construction, and a V-shaped comb or grate for preventing the roll from clogging.

In the drawings which illustrate our inven tion and make part of this specification, Figure 1 is a top view of our improved cleaner. Fig. 2 is an end viewthereof. Fig. 3 is asection of the same in a plane indicated by the line was, Fig. 1. Fig. 4 is an axial section of the cleaning-roll. Fig. 5 is a perspective view of the V-shaped comb or grate.

Like letters designate corresponding parts in all the figures.

The coal as it comes from the screen above our cleaner falls into the top of an inclined chute, A, mounted on a suitable frame. Near the upper end of the chute, and just below the place where the coal falls, is an opening through which extends a segment of a revolving cleaning-roll, B, constructed in accordance with our invention. -This roll is composed of disks 0 O and flanges D D, arranged alternately on the shaft E of the roll. The disks 0 C have smooth unbroken peripheries, and are preferably beveled at their peripheries. Each disk may be beveled on one or both sides; or it may gradually increase in thickness from the periphery to the eye. The

plates or flanges D D are of greater diameter than the disks 0 O, and are constructed with teeth a a, of suitable shape, substantially as shown, 011 their peripheries.

The spaces bej nate flanges will alternate, as will be readily understood.

. C O, and the slanting edges of the teeth may also be beveled. The teeth, which at their points are as wide as the flanges are thick, are

beveled gradually from their points down to their junction with the intermediate beveled spaces. This construction of the teeth lessens the liability of breaking theteeth at the points.

This polygonal shape is superior to a circular shape of the shaft, as the disksv and flanges are held much more firmly and steadily on the shaft; also, by making the flanges with a number of teeth equal to one-half of the number of sides to the shaft, but one form of flange is necessary to be made to cause the teeth and spaces of adjacent flanges to alternate. shaft be of octagonal shape, as we have shown, each flange would be formed with four teeth.

Thus, if the Then b lacin each flan e on the shaft, one

The peripheries of these outside hubs are made of suitable shape to receive a wrencha hexagonal shape being a proper oneto permit of their being readily screwed or unscrewed. Their eyes are suitably formed to fit over the polygonal and screw portions of the shaft. The shaft E is extended at either end to receive a pulley, d, or other means for transmitting motion to the shaft.

At the opening in the bottom of the chute A, through which a segment of the roll B extends, each edge of the chute is made of notched or comb shape. The notches c 0 may be made in the chute itself; or they may be made in the plates attached to the bottom of the chute, depending on the material of which the chute is made. If the chute itself should be made of iron or steel, the notches might be cut in the chute; but if made of wood, the notches should be made in metal plates fixed to the chute. These notches are made of sufficient depth so that the spaces between them shall nearly reach to the disks 0 G, and so that the flanges D D may revolve in the notches. The spaces between the notches are of a width to correspond with the space between adjacent flanges, and the width of the notches depends upon the thickness of the flanges. The object of these notches is to prevent the coal from falling through the spaces between the flanges where they project beyond the disks. As the coal falls from the screen above, it descends down the chute and passes over the revolving roll B. The coal passes across the roll; but the culm and slate fall through between the disks and flanges. The beveled edges of the disks and flanges, together with the teeth, serve to turn the slate edgewise and cause it to fall more surely between said disks and flanges. Actual practice has demonstrated that fully three-fourths of the slate will be removed by a single passage over this roll. This cleaner is equally applicable to stove, chestnut, and other kinds of coal.

To prevent the spaces between the disks and flanges from clogging, we make use of a V- shaped comb or grate, F, such as is shown in Fig 5. The bottom of this comb is of any suitable thickness, and the triangular teeth or bars f f are made of a length to suit the diameter of the roll 13. They are long enough to reach almost to the peripheries of the hubs b b, and are of a thickness to suit the spaces between adjacent disks and flanges. The distance between the teeth ff depends upon the thickness of the disks and flanges. This V-shaped comb is placed directly under the shaft E, where it will not interfere with the falling culm or slate, and it is evident that it will force from between the disks and flanges any materials which may become clogged therewithin.

All the various parts of our invention may be made of cast-iron or steel, or of other materials suitable to the functions of the undivided parts.
